No one is immune to a bargain — not even those who can spend GBP 30,000 on a watch. At Watches of Switzerland, an authorised dealer, an Audemars Piguet Royal Oak automatic in rose gold sells for GBP 42,600, but the same watch is on offer at "grey market" website Chrono24 from US dealer Watch My Diamonds for USD 34,850 (GBP 27,227). It is impossible to ignore that the grey market is becoming a powerful force in the watch industry, which is worth USD 62.5bn, according to Euromonitor.

The world’s online shopping giants are following smaller web retailers into what might appear to be the merchandising past. Amazon, Alibaba and most recently JD.com, are operating brick-and-mortar stores, joining companies such as the formerly web-only Warby Parker and Outdoor Voices and reoccurring pop-up events by the likes of Gymshark and Aday. Even Tencent, the Chinese games and social media giant, is doing deals in retail.

Online luxury sales jumped by 24 percent this year, according to a recent study by the consulting firm Bain & Co. and the online sales of personal luxury goods are expected to make up 25 percent of the market by 2025.
